Subject: More Ruminations on Fritz 5 SSDF strength

Having recently taken up the Najdorf from the black side, I tested
the opening by playing many games against the computers on FICS.
I was getting crushed repeatedly in blitz, especially by computers
playing the Bg5 line.  In particular, I remember getting hit with
knight sacs on b5 time after time.  But the experience got me to
thinking about how much stronger computers are in open and sharp
tactical positions.  I've never heard anyone dispute this, and isn't
it logical that programmers would try to get their programs to go
into those types of positions, either by playing certain openings,
or by algorithms that favored open positions?  If so, then Fritz 5,
supposedly being the fastest searcher, should do well when playing
other computer programs.  If all the chess programs are aiming for
sharp open play, the program that finds more tactics should win.

Thus, the #1 ranking on the SSDF list.  However, it's hard to say
if other more positional programs might do better against humans.
At least, a lot of people have pointed to some positionally ugly
Fritz 5 moves and claimed that it was easy to draw against Fritz 5,
or that so and so slow searching but positionally smart program
could hold its own in a small match.  <Continued Next Post>
